i did give a plane a thickness by going on edit mode and extruding and it doesn't crash anymore maybe because simple plain has in computer world 0 thickness, I hope this helps to fix the issue.

first have extruded and it works
second is a simple plane and it crashes

Could you add a simple blend file too? Thanks!

mds->fluid (fluid*) is NULL in manta_step, thus in uploadfluidsflow, thus in manta_get_phi_in(MANTA *): and then in MANTA::getPhiIn:
added trace in the post ^.

`mds->fluid` (`fluid*`) is NULL in `manta_step`, thus in `uploadfluidsflow`, thus in `manta_get_phi_in(MANTA *):` and then in `MANTA::getPhiIn:` added trace in the post ^.

@sebbas: I recall there where issues with zero volume domains, mind checking?

mds->fluid is set to NULL in BKE_fluid_reallocate_fluid, because the min resolution is 0. However, the rest of the code cannot deal with the situation.

Also BKE_fluid_modifier_init returns a bool which probably indicates something like success. But the return value is never checked.
